Laptop doesn't recognise new battery

[captlee]

Installed new battery but it is not recognized.  Ran HP Support Asst. and it stated no  battery detected.  Ran HP Hardware diagnostics and it stated the the battery was fine and it passed along with testing the power adapter which also passed.  This all happened after getting a CMOS 502 error, in which I bought a new HP replacement battery.  After replacing the Battery, I no longer get the CMOS error, but when the computer is on, the battery meter showed 39%, plugged in.  Now I'm down to 30% and it is still not charging.

Forgot to add in my question.  How do I get the laptop to recognize the battery?  Any help would be appreciated.

Did you make any software or hardware changes on your PC?

Check for the windows update?

No Changes to software or hardware, other than replacing battery.

It auto updates regularly.

BIOS version F.08  Downloaded a new BIOS but wouldn't update since it was version F.04

Ran a different diagnostic on boot up (the one where you tap the esc key to get system info,etc.), not the one I downloaded recently, and battery test failed because of blown fuse (42). 

Reran the new downloaded diagnostic and the battery was fine.  HP support asst. still can't detect a battery, but battery meter shows about 25% (plugged in).

My next step is to look for info on this fuse error, I recall seeing something about it.

Hi@captlee,

I appreciate your efforts to try and resolve the issue, and in order to fix this issue,  your computer needs to be serviced.  As we have limited support boundaries in the support community as of now,

As this is a hardware issue, I'd suggest youContact HPin your region regarding the service options for your computer. 

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile Name, you should see a little blue envelope, please click on it.   

Have a great day!

Thanks for the reply.  I am at a loss here.  Was finally able to download an updated BIOS to F.15.  The hoops HP makes one jump through are amazing.  After clicking to go to a third party web site to D/L the thing you need, you get an error page.  This happened numerous times.  I believe only through luck did I find I have to download a HP downloader to download the update.

After reading the boards about the blown fuse issues people are having with their batteries, I thought about what a fuse does.  Its supposed to protect the circuit and components from frying by opening the circuit stopping the voltage.  Now if the fuse is blown and you now have an open circuit, how can the computer detect the battery and its current voltage level.  You would need a closed circuit to do that.  (Think of putting only one lead from a voltmeter on a battery and expect to get a voltage reading.) I think that you are right that this a hardware issue, but not a battery issue.  One would think that HP would of solved this blown fuse problem after all the posts, other than saying you need another new battery.  With my last HP notebook, I went through six batteries in two months before the vendor said enough is enough, no more batteries for you.  I am going to try one or two other  things before I contact HP support, since I believe that they will tell me to buy another new battery.  Will keep you posted.

Hi@captlee,

You have done the basic troubleshooting as per the document and the notebook needs to check to get to know its hardware is faulty, not a software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.

Ran the trouble shooting guide that came with the new battery, remove battery, power on with the adapter.  Computer booted with CMOS 502 error because of no battery.  Reinstalled battery and it boots up normally, with battery detected but not charging.  This proves that the A\C adapter in working.  Their next suggestion is to down load the manufacturer's latest power management driver.  I didn't know such a driver existed, but I guess there is a driver for almost everything in a computer.  Does HP have a power management driver and to save me time, where would I find it?

Thanks .

Hi@captlee,

I understand you are getting plugged in not charging error on your laptop.

 Did you make any software or hardware changes on your laptop?

Have you tried charging your laptop using a different adapter?

As you mentioned you are getting error plugged in charging on your PC.

Check if the pin inside the DC or charging port is bent or broken.

Please perform the below-shown steps to resolve the issue:

Step 01. Click on the Start Button

Step 02. Type "Device Manager" in the start search box & open the Device Manager

Step 03. Look for Batteries and expand it by click on the + symbol on the left

Step 04. Right Click on "Microsoft ACPI Compliant Control Method Battery" & uninstall

Note: This Battery driver will get reinstalled automatically when you restart the Notebook again

Step 05. Please Shutdown the Notebook

Step 06. Please remove the Battery and unplug the Power Adapter

Step 07. Press and hold the Power Button for a full 1 Minute

Step 08. Go ahead and put back the Battery and connect the Power Adapter

Step 09. Look for the "Plugged In Charging" message on the Battery icon

Also, try performing a hard reset on your laptop and check if it helps.

Please Shutdown the Notebook

Please remove the Battery and unplug the Power Adapter

Press and hold the Power Button for a full 1 Minute

Go ahead and put back the Battery and connect the Power Adapter

Look for the "Plugged In Charging" message on the Battery icon.

If the issue persists try updating BIOS on your PC and check if it helps.

Just upgraded to Win 10 21H1

BIOS v. F.15, just updated this week.

The only other adapter I have is from my old dv7, not sure if its compatible.

Followed the instructions you gave me, still the same, battery not charging, plugged in, now down to 11%.

After restart, I checked for driver updates for the Microsoft ACPI Compliant Control Method Battery and the adapter also, both results is that I have the best and latest drivers, so no update necessary, even though they have dates of 2006.

Again, thanks for your help.
